The Rise of Assurance Reporting in ESG

As sustainability reporting in the Philippines matures, the next frontier is assurance reporting—the independent verification of ESG disclosures by accredited third parties.

What used to be an optional step is quickly becoming a requirement. Globally, the IFRS S1 and S2 standards emphasize assured, investor-grade ESG reporting, while the Philippine SEC continues to push for greater data credibility and transparency.

What Is Sustainability Assurance?

Sustainability assurance is the process of having an independent party review and verify a company’s sustainability or ESG report. The goal is to ensure the data presented—whether on emissions, energy use, diversity, or governance—is accurate, complete, and consistent.

In practice, it works like financial auditing—but for non-financial data. Assurance providers evaluate whether ESG information is prepared according to recognized frameworks such as:

• IFRS S1 & S2 (formerly under ISSB)
• GRI Standards 2021
• TCFD recommendations

Why Assurance Reporting Matters

1. Investor Confidence

Verified sustainability data reassures investors that a company’s ESG performance is reliable and comparable—not marketing fluff.
In PwC’s Global Sustainability Reporting Survey 2024, over 70% of investors said they are more likely to fund companies whose sustainability reports are externally assured.

2. Regulatory Preparedness

The SEC and other ASEAN regulators are moving toward mandatory assurance for sustainability disclosures. Companies that prepare early will avoid last-minute compliance pressure.

3. Reputation and Trust

Assured reporting builds stakeholder trust—internally and externally. It signals transparency, accountability, and good governance.
